Entering an equal sign followed by another cell's address in a blank cell exports the referenced cell's contents to the new location in Excel. However, using this technique creates a link between the two cells, so changes in the original cell are reflected in the export location. If you only need to extract data, Excel 2013's Paste Values feature enables you to do so without maintaining a link between the two cells. If you later change or delete the original data, the exported location does not change.

Click the cell that contains the data to be exported and press "Ctrl-C."

Click the cell where you want to export the data.

Click "Paste" from the Home tab's Clipboard group and select "Paste Values." The original cell's data is copied to the new location. You are free to delete or modify the original cell's contents without changing the copied data.
